Some macOS 12.2 Users Experiencing Bluetooth-Related Battery Drain Issue During Sleep Mode

My AirPods Pro do that with my phone - really annoying when I'm in a normal call and the line goes dead because Apple decide to re-route to the Airpods - in their case...
I have reported a bug in Monterey 12.2. I am one of the Mac users, so we could report a bug to the macOS team to fix it.
Apple released macOS Monterey 12.2 earlier this week, and some Mac users who have installed the software update are experiencing excessive battery drain during sleep mode, seemingly due to Bluetooth accessories frequently waking the computers.
The issue has been reported by users across the MacRumors Forums, Reddit, and Twitter over the last several days, but it is unclear how widespread it is.
Affected users say their Mac's battery life drops from 100% to 0% while in sleep mode overnight since updating to macOS 12.2. A few users tried to identify a cause in Terminal and found that Bluetooth accessories are frequently causing a "DarkWake from Deep Idle" that results in the Mac repeatedly waking from sleep, which drains the battery. The issue appears to be affecting both Intel-based Macs and M1-based Macs.
Users report that the issue ceases when Bluetooth is disabled or when all Bluetooth accessories are disconnected from the Mac, but this is not an ideal solution.
Apple seeded the first beta of macOS 12.3 earlier this week, but it is not immediately clear if that version fixes the issue. We have reached out to Apple for comment on the matter and will provide an update if we hear back.

As a temporary (I hope) workaround, have used Shortcuts to create two shortcuts: one turns off BT, the other turns it back on. They live in the dock. A quick and easy toggle. But yeah, I hate it.
First I will say I am not having this problem on my M1 MBP running 12.3, so I can only speculate. Has anyone kept activity monitor running and seen what processes are using so much energy? I literally get 2 days usage out of a battery charge, so complete drain overnight? That is way more than just system wakes. If it were me, I would be more concerned that I got a virus or someone put on a crypto miner, I couldn't drain my battery overnight if I left it on with the screen at full brightness and playing movies that I was not watching.
So it is as also reported by others fixed in the next release. Problem is with 12.2 with any BT device connected.
I would expect that Apple will release fix earlier - usual 12.x.1 released very quick after 12.x
Umm...you know that there is a toggle in the menu bar to switch BT on/off, right? Why duplicate the same functionality?
I'm still curious about what process is running down the battery overnight. And for the record, I only use bluetooth for headphones, As I said, I cn only speculate. But if you do have the problem please leave activity monitor on, and see what is reported for high energy use. Many thanks
Whatever processes you have on your computer. The issue with BT causes computer to enter sleep-wakeup never ending loop. Then depending what you have normally running on your computer when awake it will run. If you have HDD connected it will stop-start hundreds times per night etc. There is no point at all to monitor activity monitor for this issue.
You are asking why when you start-stop computer every every few seconds it runs out of battery quick... when it is obvious
Am I the only one who also has issues with Bluetooth-related features, like Universal Clipboard or Unlock with Apple Watch since 12.2? It was working fine on 12.1
I think you may be trivializing the question. You can literally leave a MBP M1 on with the screen on and doing some random tasks and it will not drain the battery overnight. So somehow waking the screen will? and processes don't "run" just because the Mac is on, if they are not doing anything, they sit idle (except for chrome, unless they finally fixed it). so maybe waking with chrome running drains the battery. Mail programs might try to do a refresh when woken, but that won't happen if the Mac is at the Lock Screen. But Numbers, Word, and the like will sit idle. Allowing the hard disks to sleep when necessary, will not wake them until you actually try to use them. And if you are at a Lock Screen, few things will refresh anyway. So, maybe it is obvious to you, but it doesn't make sense to meWhatever processes you have on your computer. The issue with BT causes computer to enter sleep-wakeup never ending loop.

yes, you are. Seriously, it worked fine for me, and still working fine on 12.3
you are right - and indeed everybody will experience this issue different. But this thread is about BT preventing computer sleep in 12.2 not about what programs cause my battery to run out quick
It is not important in this context if my laptop drains completely overnight or by 10%. The problem is that it can't enter proper sleep mode. When it does there is almost no battery drain at all.
I opened my big mouth and now it's NOT THE FIX. 12.3 doesn’t seem to be the fix. I checked the laptop this morning. Im also recieving a battery service warning. lol.... I changed my battery settings now though. Maybe the whole issue is a simple change of battery preferences? I wasn’t allowing my disk to sleep, plus... the POWER NAP while on battery was off. On my other MacBook thats usually on beta it still has not experienced that drain issue... the firmware is the same "
System Firmware Version: 1731.100.124.0.0 (iBridge: 19.16.14214.5.4,0)
OS Loader Version: 540.100.6~27"
What I do know for a fact is my betaMBP is never connected to my Dell Q2720(VIA Thunderbolt 3) or my Belkin thunderbolt 2 dock.....Maybe it’s an issue with connected devices? My display is always turned off at night and no charging occurs(because its already a full battery). My dock is not connected to ethernet either. So What I will do tonight... set up my betaMBP where I usually have my main MBP and leave it over night in the same conditions. For my Main MBP I will just leave it charged and to the side over night. Basically im swapping their roles to see if its possible that its one of my connected USB devices is causing the issue. Sound good?

The issue is casued by macOS doing never ending "DarkWake from Deep Idle" when in sleep mode. Various people experiments showed that it is related to bluetooth - turning BT off "fixes" the problem. And I can confirm it from my experience.
Please note that it does not turn laptop screen on (but can cause external monitor to leave sleep mode) It will wake up any connected drives. And for short moment run whatever software is running normally on your computer. After moment of activity computer goes sleep again only to repeat all process again in never ending loop.
People only notice it when running on battery (it will drain) or when having external HDD connected - they spin up and down all the time. If you are running on AC and do not have any HDD you probably wont see any noticable difference.
I’ve had the Dock connected to the MBP but it hasn’t actually been in use. No ethernet connected, no displays, not even my hard drives are connected over night. I used to leave it over night but I would wake up to 50 notifications that it was disconnected without ejecting it. Well.... my Beta MBP(i5) was on battery(NOT AC) and didn't experience the drain issue at all. BT was on and all that. So this is weird...

Do you have anything connected to BT? Maybe it does not happen when nothing is connected - have not tested. I use multiple BT devices and now only option is to turn BT off before entering sleep (which I have automated so not massive deal).
I believe the answer is NO I didnt have anything connected directly, but I was using universal control cause its really ****ing awesome. I dont think UC counts as connected. I think it disconnects as soon as you close the lid. I guess I should switch my magic keyboard and mouse rather than the display/dock tonight to see.
In my case, I use a BT Magic Mouse and have the drain only after updating to 12.2 last Wednesday. The battery drains during sleep even if I'm not logged into my user account - so it has nothing to do with programs running for me. If I turn off my BT Magic Mouse there is no drain during sleep. If I turn off Bluetooth altogether before closing the lid there is no battery drain. In my case, the battery loses 10% every hour because of 60 bluetooth wakes/hour. It's not just that the computer wakes and uses battery, but each time it re-enters sleep, I believe it must write the current awake state and memory state to the boot disk. I went to the Genius Bar yesterday and they told me to do an internet recovery boot and reinstall the system on top of existing. This did not solve the problem.
Correct - just running this stop-start loop uses energy. If you are logged in and have stuff running it only speeds up all process of draining battery.
The only real solution is to stop the loop from happening - this is Apple job as this is obvious bug introduced in 12.2 - BTW the same behaving bug happened in High Sierra.
In the meantime as you and many others noticed turning BT off prevents it from happening. Either you do this manually before sending your computer to sleep or you can automate it. There are few solution flying around but I used mine which so far does the job (turn BT off when going to sleep and turn it back on when waking up):
Monterey Bluetooth wake issue.
In my case it happens when on battery or on AC power - and if I have external disk connected it starts/stops every few seconds. Not acceptable. And of course when on battery it kills it quick. Turning BT manually off before going sleep "fixes" the problem but automation is always better in case...

Nah, I haven't read any.
I feel I get the gist anyway.
1. Create great products, and people will buy them. Create incredible products, and a lot of people will buy them. Get too caught up in profit seeking from your customers, thus letting your products become compromised, and you will die a death of a thousand cuts.
2. It helps to be a bit off an *ssh*le if you want to get your product ideas rolling.
3. Steve is a once in a generation genius.
It seems to me that little Timmy only has part 2. down pat. And Apple perhaps could heading for the death of a thousand cuts sometime in the future, but aren't yet, as they are still head and shoulders above the competition (entirely due to Steve's genius products still chugging away with the constant little upgrades that any decent engineering team could do). But by crickey, what on earth is going on with the software division!!!
In a lot of ways the iPhone was a dual edged sword. It created a huge halo effect, enormous revenues (with high profit margins) and an ecosystem with 10 of Millions of users/customers for software. But it also created a huge ship that has to get larger and larger to survive. How do you out due the iPhone? So instead it's this constant focus on growing revenue. It makes definitely changes the company. That being said most of Apple products are better than they were 20 years ago. The functionality we rely on now, would been like magic in the 1990s. All of the magic leads to incredibly complicated solutions. I do think MacOS could benefit from a period of focus on stability and performance. Would have made sense to use the ARM64 transition to do that.
I have this bug too. Apple has had me reset a couple of things and reinstall the OS. nothing has worked. last night the MBP 16 2019) went from 100 to zero overnight with a logitech MX mouse. i am now going to go a night with bluetooth off. I also have a genius tech appt on Sunday afternoon.
i should note they have not acknowledged a bug in any way. they are very very nice but they seem to want to blame my battery.
